In an interview with National Public Radio (NPR), Carly said she wrote this song about Cat Stevens while she was waiting for him to pick her up for their first date. (thanks, Darrell - Dallas, TX)

This song was made famous by a Heinz ketchup commercial in the late '70s. Heinz ketchup is thick and pours very slowly. In the commercial, a person would be shown waiting for the ketchup to come out of the bottle as the chorus of "Anticipation" played in the background. For this reason, many people think of this song as "The Ketchup Song." (thanks, Andy - Arlington, VA)
